We architect and deploy custom Layer 1 and Layer 2 solutions that solve specific business challenges, not generic use cases. Our development is driven by your requirements for throughput, finality, and governance.
Self-Sovereign KYC Identity Storage
Custom Blockchain Development
Build secure, scalable, and purpose-built blockchain networks tailored to your business logic.
- Consensus & Protocol Design: Custom
Tendermint,Polkadot Substrate, orEVM-compatible chains. - Smart Contract Integration: Native support for
Solidity,Rust (ink!), orCosmWasm. - Node Infrastructure: Full validator setup, RPC endpoints, and block explorer deployment.
- Cross-Chain Bridges: Secure, audited bridges to major networks like Ethereum and Solana.
Deliver a production-ready mainnet in 8-12 weeks, with a clear roadmap for upgrades and ecosystem tooling.
Architectural Components We Deliver
We build the core infrastructure for self-sovereign KYC, delivering production-ready components that ensure compliance, security, and seamless user onboarding. Each module is designed for integration within 2-4 weeks.
On-Chain Identity Registry
Deploy a custom, gas-optimized smart contract registry (ERC-725/ERC-734) to anchor and manage verifiable credentials. Supports zero-knowledge proofs for selective disclosure and integrates with existing KYC providers.
Credential Issuance Gateway
A secure, audited API gateway for KYC providers to issue W3C Verifiable Credentials. Features automated compliance checks, revocation list management, and multi-chain signature support (EVM, Solana).
Zero-Knowledge Proof Engine
Implement zk-SNARKs (Circom) or zk-STARKs for privacy-preserving KYC checks. Allows users to prove credential validity (e.g., age, jurisdiction) without exposing underlying data, reducing liability.
Decentralized Identifier (DID) Resolver
A high-availability service resolving did:ethr and did:web identifiers to their associated public keys and service endpoints. Essential for wallet integration and cross-platform identity.
Compliance & Audit Dashboard
A real-time admin dashboard for monitoring credential issuance, user consent logs, and regulatory reporting. Provides immutable audit trails for financial authorities (FATF Travel Rule).
Cross-Chain Attestation Bridge
Enable portable KYC status across EVM, Cosmos, and Solana ecosystems using our lightweight message-passing bridge. Users maintain a single verified identity for all your dApps.
Business Outcomes for Your Platform
Our self-sovereign KYC identity storage solution delivers measurable business value by reducing compliance overhead, accelerating user onboarding, and unlocking new revenue streams.
Accelerated User Onboarding
Reduce KYC verification time from days to minutes. Our reusable identity attestations allow users to onboard to your platform in under 60 seconds after initial verification, increasing conversion by up to 40%.
Dramatic Compliance Cost Reduction
Eliminate recurring per-user KYC verification fees. Our one-time, portable identity model cuts ongoing compliance costs by over 70%, turning a cost center into a competitive advantage.
Enhanced Security & User Trust
Implement zero-knowledge proofs and decentralized storage for maximum privacy. Users control their data, reducing your liability while building trust through transparent, auditable compliance logs.
Unlock Cross-Platform Revenue
Enable seamless identity portability across your ecosystem. Verified users can instantly access new products (DeFi, NFTs, gaming) without re-verification, driving higher lifetime value and engagement.
Future-Proof Regulatory Compliance
Stay ahead of global regulations (Travel Rule, MiCA) with a flexible, upgradeable identity framework. Our modular design allows rapid adaptation to new jurisdictional requirements without platform rewrites.
Enterprise-Grade Integration
Deploy with enterprise SLAs and dedicated support. Our APIs integrate with your existing stack in under 2 weeks, backed by 99.9% uptime and 24/7 technical support for critical compliance operations.
Build vs. Buy: The Chainscore Advantage
A detailed comparison of the costs, risks, and time required to build a self-sovereign KYC identity storage system in-house versus leveraging Chainscore's production-ready platform.
| Factor | Build In-House | Chainscore Managed Service |
|---|---|---|
Time to Production | 6-12 months | 4-8 weeks |
Initial Development Cost | $250K - $600K+ | $50K - $150K |
Security & Audit Burden | High (Unaudited Code Risk) | Low (Pre-Audited, Battle-Tested) |
Ongoing Maintenance & DevOps | 2-3 Full-Time Engineers | Fully Managed by Chainscore |
Compliance & Standards Updates | Your Responsibility | Included & Proactively Managed |
Uptime & Reliability SLA | You Build It (No SLA) | 99.9% Guaranteed Uptime |
Integration Complexity | High (Custom Wallets, SDKs, APIs) | Low (Plug-and-Play SDK & APIs) |
Total Cost of Ownership (Year 1) | $500K - $1M+ | $80K - $200K |
Support & Incident Response | Internal Team Only | 24/7 Engineering Support |
Our Development & Integration Process
A transparent, milestone-driven framework designed for rapid deployment and enterprise-grade security. We focus on delivering production-ready KYC identity storage that integrates seamlessly into your existing stack.
Discovery & Architecture Design
We conduct a technical deep-dive to map your compliance requirements and user flows. We deliver a detailed architecture document outlining the optimal storage solution (ZK-proofs, encrypted vaults), smart contract standards (ERC-725, ERC-1056), and integration points.
Smart Contract Development & Auditing
Our engineers develop and gas-optimize the core identity logic using Solidity 0.8+ and OpenZeppelin libraries. Every contract undergoes rigorous internal review followed by a formal audit from a top-tier third-party firm before deployment.
Backend Integration & API Development
We build the secure off-chain infrastructure, including encrypted data vaults, key management services, and verifiable credential issuers. You receive a comprehensive REST/GraphQL API for seamless integration with your frontend and existing KYC providers.
Staging Deployment & Security Testing
We deploy the complete system to a staging environment matching mainnet conditions. We execute penetration testing, load testing, and a full compliance checklist with your team before proceeding to production.
Production Launch & Ongoing Support
We manage the mainnet deployment, configure monitoring (alerting, analytics), and provide 24/7 incident response. Includes a 30-day intensive support period and options for long-term maintenance and upgrade plans.
Self-Sovereign KYC: Technical & Compliance FAQs
Technical and regulatory questions our enterprise clients ask before implementing a self-sovereign identity solution.
A complete, production-ready Self-Sovereign KYC (SSI) system with identity storage typically deploys in 4-6 weeks. This includes architecture design, smart contract development, frontend integration, and a full security audit. For a basic MVP with core verification flows, we can deliver in 2-3 weeks. Timelines are fixed-price and guaranteed in our SOW.
